Need Help Finding "Specialty Screws"

Recommended Posts

Well I need to find some screws and I'm not having any luck. They are allen head machine-type screws for the chassis of an amplifier.

I've searched high and low locally....from big box stores to mom-&-pop hardware stores to RC Hobby shops. Everything I've found is either too large or doesn't have the right thread pattern.

Anybody have an idea of a good store or website to look on to find somewhat obscure screws ?

Fasten-all or McMaster Carr.

Do you know the thread size and pitch?

Well, if my measurements are correct the threads are 3/16" in diameter with a pitch of .0625"

Did you try partsexpress?

I found some of mine non-standard screws there...

Their "screw" category doesn't have anything close to what I need..... :(

Brad, there are some Fastenal locations near you in Angola and Kendallville. Try there. I have used them in the past for work and they can get anything I needed.

Good call!

I work in Kendalltucky so I'll just swing by there on my way in.

If that doesn't work I'll try some of the other places you guys have recommended.

Thanks !

What kind of head is on it? You said an allen head, but is it like a button, cap, countersunk? I work at a hardware store and can normally get just about anything. Let me know, I go to work at 4 EST so I could check tonight. Get back to me.

Well....I handed Fastenal the screw that I need more of and they basically laughed and said "good luck with that".......

The head looks essentially like this;

(only it's gloss black)

The guy at Fastenal said it's a #4 screw. It's about 1/4" to 5/16" long. It appears to be self-tapping (but not self-drilling/piercing, it's flat on the end)

The problem is the threads....it's extremely course. Apparently having this course of thread on such a small screw is pretty "rare". Can't take a good pic....but looking at it from the side it only has 5 "peaks" down it's entire length.

What amplifier is it for? I have some like you are describing from an Infinity amp.

BTW, worst case scenario, you can always tap them to a proper thread.

Ok that is what I call a cap head. The guy said it was a #4? Earlier you said it was about 3/16 which is a #10... I know we're nit pickin' here but I'm trying to get this right.

I looked in our catalog tonight and I can get you everything from a #2 all the way to a 3/8 with a cap head like that. Just matching the thread is going to be the problem. Also most of these are stainless so its kind of a weathered looking steel, its not exactlly black. Let me know if you want more information.

BTW, I know I can get black cap screws like that, just not a gloss black. Its more of what you pictured above.

The ones he's talking about aren't an actual machine thread. They are self-starting/tapping sheetmetal type screws. These are common to all makes of amplifiers.

Ok. That makes sense then, its more of a sheet metal screw, I just realized he said that, but I didn't really put two and two together. I'll see what I can dig up.

Coustic Design Reference.

Stupid thing is about 2 months ago I sold some blown DR's I had....if I was smart I would have pulled the screws from one of those amps before I sold them :(

Also thanks for helping kbkid....let me know what you find.

Alright I'll see if I can log onto our store's online catelog and see what I can come up with.

Yeah, but they have a cut in the end to allow for self-tapping and it's flat.

I think .5" might be a little too long though.

But seems to be the same general type of screw that I need.

Ok, I'll keep trying. I'm working on digging up black ones though.

Wow 1/4" isn't much, espically since your having a cap head like that.
